Hi folks,

I'm running a distributed system, one of the gateways seems to have
sprung a leek though and is letting some spam through which is being
caught on the other systems.  I copied the config files between the
systems to ensure consistancy when the systems were built so I'm
wondering if it could be some other weakness I haven't considered,
perhaps a time-out or setitng which causes the messages to be sent
through unscanned or part scanned perhaps?  I'm using mailwatch too
and can see the scores in the message headers, an example of one is

thanks for any help or suggestions you may offer,
